Washington (CNN) -- The Justice Department is expected to file a legal challenge Tuesday against Arizona's controversial immigration law, according to an administration official.

The law, which is scheduled to take effect at the end of July, requires immigrants to carry their alien registration documents at all times and allows police to ask residency status of people in the course of enforcing another law. It also targets businesses that hire illegal immigrant laborers or knowingly transport them.

Don't worry if you are not here illegally. Many of those jobs that supposedly "nobody wants" were once good summer and part time jobs for our kids (kids of U.S. citizens). And now that the global crooks emptied the til, U.S. Moms and Dads need some of those jobs. Get to the back of the line!
